Overview

Connecting HA Servers to the Switch describes connectivity requirements and recommendations specific to CMS High Availability (HA) systems. This information is applicable to the following DEFINITY Release 8.1 switches:

•Generic 3si (G3si)

•Generic 3r (G3r)

•Generic 3csi (G3csi)

•Prologix Release 3 (G3csi)

Switch-Over

Options

The connectivity configurations described in this chapter represent the optimal link setups for HA systems. Other switch-to-server connectivity configurations are not described herein. For information about other switch- to-server connections, see CentreVu Call Management System Switch Connections and Administration (585-215-876).

The primary purpose of the CMS High Availability offer is to ensure an uninterrupted data stream between the DEFINITY ECS and the CMS system on which the data is stored. However, some customers may also desire continuous access to their CMS data. Following a major failure event on their primary HA server, customers have the option to switch over to their secondary server for purposes of CMS data monitoring and reporting. A server switch-over should be performed only when the anticipated down time for the primary server is expected to be significant.

Customers must choose between the following switch-over options:

1.No switch-over

Customers who do not require continuous access to their CMS data can choose not to switch-over to the secondary server after the primary server experiences a major failure event. When the primary server goes down, uninterrupted collection of call data will continue on the secondary server, but the customer will not be able to access that data until the primary server is restored.
